面向离散制造物联车间的UWB实时定位系统设计

摘要

The manufacturing process of discrete manufacture is complex and varied, manufacturing resources have a wider dynamic characteristics, in view of control management manufacturing resources effectively, realization gathering real-time location data of IoMT-based workshop, A management system of resources-locating for IoMT-based discrete plant was established based on an active perception technical framework of manufacturing data, and designed a positioning system for Manufacturing resources based on UWB, improve a wavelet threshold de-noising algorithm based on adaptive threshold function and realized, can reduce the interference of external factors effectively, reduce the error of positioning, and could gathering real-time location of IoMT-based workshop, access the location of the manufacturing resources effectively, such as the staff, material, logistics vehicles, convenient for awareness and scheduling management, Finaly improve the management standard and product quality.%离散型制造业生产过程复杂多变,制造资源具有更为广泛的动态特性,为进行有效的制造资源管理控制,实现制造物联车间实时位置数据的采集,基于制造物联事件主动感知技术架构,提出了一种离散制造物联车间资源定位管理模型,设计了一种基于超宽带技术的制造资源定位系统,改进了一种基于自适应阈值函数的小波阈值去噪算法并实现,能够有效降低外界因素的干扰,减少定位误差,实现对离散制造车间制造资源的实时定位,有效获取人员、物料、物流车辆等制造资源的位置数据,便于进行资源感知和调度管理,从而提升管理标准及产品品质.
